Re: Mandy Jane's Corner

Okay I will email you shortly.(EDIT: By the way for the benefit of anyone else reading this I sent 3 questions on division by 10 which Mandy replied to with all 3 correct. I then sent some questions on multiplication by 10 and 100 and then one divide by 100 question at the end.)

Here you have simply added point zero on the end. Doing this does not actually change the value of the number, but is sometimesuseful to help with a calculation. In other words 65 = 65.0

I think the problem here is understanding the question. Do you want to have another attempt at those?

SECOND EDIT:I have sent 2 emails to you (Mandy) about this and I hope they have been of some help. Just in case they have not gotthrough here are a few notes on multiplication by 10 and 100, and division by 10 and 100.

Let us consider a number like 27.34

It can be thought of as 2 tens, 7 units, 3 tenths and 4 hundredths as shown below:

tens units tenths hundredths 2 7 . 3 4

To divide by ten the numbers go this way one space -------><--------- To multiply by ten the numbers go this way one space.When we divide by 10: tens become units, units become tenths, tenths become hundredths, hundredths become thousanths ......(etc)When we multiply by 10: hundredths become tenths, tenths become units, units become tens, tens become hundreds ........(etc)

So if we successively divide by 10:27.34 becomes 2.734 then 0.2734 then 0.02734 then .....(etc)

If we successively multiply by 10:27.34 becomes 273.4 then 2734 then 27340 then 273400 .....(etc)

Do not spend too long on these questions. If they are taking more than about 20 seconds each to do then something is wrong.
